Description

Wenglor HO08PA3 Reflex Sensor Background Suppression

Wenglor HO08PA3 Reflex Sensor Background Suppression these sensors detect distance by measuring angles. They are particularly good at recognizing objects in front of any background. The color, shape, and surface characteristics of the object have practically no influence on sensor-switching performance. Also, these sensors don’t influence each other if their light spots are pointed at the same spot or against each other. Reflex sensors with background suppression detect and measure objects contactless and detect them in front of any defined background. They work with red light, infrared light, blue light, or laser light. Thanks to the principle of angle measurement, the color, shape, and object surface have no influence on the switching behavior of the sensors.
